Everyone has old cans of leftover paint. While local regulations in most municipalities do not consider latex paint to be hazardous waste, they will not accept liquid paint in the trash or to be taken to the landfill. They demand that the paint be either “dried out” or solidified, even water-based paint. A time-consuming and messy process, unless you use an efficient latex paint hardener.
Latex paint is an “oil-in-water” emulsion. Basically there are microdroplet of hydrocarbon latex suspended in water. They usually recommend adding kitty litter or sawdust to solidify the unused paint but that is only practical if the can is half-filled or less. (It takes about ½ – ¾ gallon of kitty litter to solidify a ½ gallon of unused paint.) For more full cans you now have to pour paint into a second container, add absorbent and make a bigger mess!
Waste Lock® Paint Hardener Solutions
A better solution is to use our Waste Lock® 770 superabsorbent polymer and latex paint hardener additive.The Waste Lock® 770 superabsorbent polymer aggressively absorbs the water phase on the emulsion leaving the latex phase to bind to itself. The paint turns into a mass of rubber with little or no expansion of the waste volume.
Simply add about 4 oz of Waste Lock® 770 to about 3/4’s gallon of unused latex paint. Disperse the polymer throughout the can with a stirring stick and wait about 5 minutes. Viola! Solidified paint can ready for the trash!
